Separation of Enantiomers and CD Spectra of Au40(SCH2CH2Ph)24: Spectroscopic Evidence for Intrinsic Chirality

Chirality unveiled: Thiolate‐protected Au40(SR)24 clusters were enantioenriched using an HPLC approach. CD spectra show strong mirror‐image responses, indicating the intrinsic chirality of a cluster of unknown structure protected with achiral ligands.
